[0002] The advent of the first camera phone has brought a qualitative leap to people's lives. Along with the rapid development of camera technology, the emergence of dual-camera mobile phones has brought an even richer photography experience to people.

[0003] Nowadays, many manufacturers are no longer satisfied with dual-camera technology and have started to move towards multi-camera technology. In mobile phones with multi-camera functions, a main camera is responsible for taking pictures, and sub-cameras are responsible for assisting in imaging, such as zooming, increasing the amount of light entering, color adjustment, and detail calibration. If multiple imaging effects need to be integrated in a mobile phone, it is necessary to add multiple sub-cameras and sub-chips for pairing in the mobile phone. In this way, it will inevitably lead to an overly large volume of the mobile phone, which goes against the current market demand trend of lightness and thinness. Moreover, the setting of multiple sub-chips will undoubtedly increase the cost of the mobile phone. Summary of the Invention

Obviously, the embodiments described below are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0038] In the description of the present invention, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component.

[0039] In addition, terms such as "long", "short", "inner", "outer", etc. indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or component referred to must have this specific orientation and be constructed and operated in this specific orientation, so it should not be understood as a limitation of the present invention.

[0040] The technical solution of the present invention will be further described below with reference to the drawings and specific embodiments.

[0041] The present invention provides a lens module, which includes a main camera module 10 and an auxiliary camera module 20 disposed on a support surface.

[0042] In this embodiment, the lens module is applied to a smart phone. Therefore, the support surface can be the inner wall of the smart phone housing or a support such as a support frame added in the smart phone, and no further limitation is made here.

[0043] Please refer to Figure 1 、 Figure 2 , the main camera module 10 includes a main chip 12 and a main camera lens 11, and the main camera lens 11 is used to collect a second light beam and inject it into the main chip 12 for imaging.

[0044] The auxiliary camera module 20 includes a sub-chip 221, a switching mechanism, and an auxiliary camera lens group.

[0045] The auxiliary camera lens group includes at least two auxiliary camera lenses 21; the switching mechanism is used to selectively switch and move each auxiliary camera lens 21 to a specified position, and the specified position corresponds to the installation position of the sub-chip 221; the sub-chip 221 is used to image the first light beam collected by the auxiliary camera lens 21 located at the specified position.

[0046] In one alternative embodiment of this embodiment, each auxiliary camera lens 21 is arranged in the same circumference as the specified position; the switching mechanism controls the switching of each auxiliary camera lens 21 along a circular switching path.

[0047] In another alternative embodiment of this embodiment, each auxiliary camera lens 21 can also be arranged in a rectangle, polygon or even irregular shape, as long as the switching mechanism can drive the auxiliary camera lens group to move according to a specific switching path, so as to selectively move one of the auxiliary camera lenses 21 to the specified position to cooperate with the sub-chip 221.

[0048] In this embodiment, taking the example that each auxiliary camera lens 21 is arranged in the same circumference, the switching mechanism will be further described.

[0049] In this embodiment, the switching mechanism includes a driving rotating member 231 and a driven rotating member 232, and the driving rotating member 231 is meshed with the driven rotating member 232.

[0050] Please refer to Figure 1 and Figure 2 In one optional implementation manner of this embodiment, the driving rotating member 231 and the driven rotating member 232 form an internal meshing gear set; the driving rotating member 231 is an external gear, and the driven rotating member 232 is an annular sleeve sleeved outside the driving rotating member 231, so that the driven rotating member 232 and the driving rotating member 231 are coaxial.

[0051] In this implementation manner, to ensure the compactness of the arrangement between the main camera module 10 and the auxiliary camera module 20, the driving rotating member 231 is an annular body, and the main camera module 10 is arranged in the middle of the driving rotating member 231. Thus, when the driving rotating member 231 rotates, the main camera module 10 does not rotate accordingly.

[0052] The driven rotating member 232 is in a hollow cylindrical shape, the auxiliary camera lens 21 is fixed on the inner wall of the driven rotating member 232, and the auxiliary camera lens 21 is fixedly connected to the driven rotating member 232 with an adhesive 2321.

[0053] When the rotating driving member drives the driving rotating member 231 to rotate, the driven rotating member 232 rotates coaxially with the driving rotating member 231 to realize the switching use of the auxiliary camera lens 21.

[0054] Please refer to Figure 3 In another optional implementation manner of this embodiment, the driving rotating member 231 and the driven rotating member 232 form an external meshing gear set; the driving rotating member 231 is an external gear, and the driven rotating member 232 has an external gear and is an annular sleeve.

[0055] Specifically, the driven rotating member 232 is an annular body, and the main camera module 10 is arranged in the middle of the driven rotating member 232. Thus, when the driven rotating member 232 rotates, the main camera module 10 does not rotate accordingly. The foregoing structure can ensure the compactness of the arrangement between the main camera module 10 and the auxiliary camera module 20.

[0056] The driven rotating member 232 is in a hollow cylindrical shape, the auxiliary camera lens 21 is fixed on the inner wall of the driven rotating member 232, and the auxiliary camera lens 21 is fixedly connected to the driven rotating member 232 with an adhesive 2321.

[0057] In this embodiment, when the rotation driving member drives the active rotating member 231 to rotate, the active rotating member 231 drives the driven rotating member 232 to rotate under the transmission action of the external meshing connection relationship, thereby switching the auxiliary camera lens 21 that cooperates with the sub-chip 221.

[0058] Further, the active rotating member 231 can rotate by itself under signal control; in addition, the active rotating member 231 can also be provided at the driving end of a rotation driving member, and the rotation driving member is used to drive the active rotating member 231 to rotate; the rotation driving member can be a rotation motor.

[0059] Based on the above embodiments, the auxiliary camera lens group includes a total of eight auxiliary camera lenses 21, and the auxiliary camera lenses 21 are arranged at equal intervals on the switching mechanism.

[0060] Further, the auxiliary camera lens 21 is an infrared lens, a telephoto lens, a wide-angle lens, a macro lens, an ultraviolet lens or a zoom lens.

[0061] Specifically, the wavelength of the infrared camera lens can be 850nm, 910nm, 940nm or 1300nm; the telephoto lens can cooperate with the main camera module 10 to achieve a focal length of 2 times, 3 times, 5 times or even 10 times; the wide-angle lens can be a lens with a viewing angle ≥ 100°, which is more suitable for taking pictures of larger scenes, such as buildings and landscapes; the macro lens can achieve a minimum shooting distance of 2.5CM, and can be used to shoot very fine objects, such as flowers and insects; the ultraviolet lens can be selected with an ultraviolet wavelength ≤ 400nm, which is suitable for shooting in environments such as the seaside, mountains, snow fields and open areas, and can weaken the blue tone caused by ultraviolet rays; the zoom lens is a lens that can achieve optical zoom.

[0062] It can be understood that the types of the auxiliary camera lens 21 are not limited to the above-listed lens types, and other types of lenses can also be selected, which will not be enumerated one by one here.

[0063] Please refer to Figure 4 、 Figure 5 The sub-camera module further includes an auxiliary camera chip mechanism 22 for installing the sub-chip 221. The auxiliary camera chip mechanism 22 is located between the switching mechanism and the support surface, and includes a PCB board 222 and a filter 224; wherein, the PCB board 222 is fixed on the support surface, and a bracket 223 is provided thereon, the filter 224 is provided on the bracket 223, the sub-chip 221 is disposed on the surface of the PCB board 222, and the sub-chip 221 is located between the filter 224 and the PCB board 222.

[0064] Based on the above embodiments, the present embodiment provides an electronic device, including the lens module provided in the above embodiments, and further including a control module; the control module can be disposed on the support surface or at a position outside the support surface, as long as it can be electrically connected to the main camera module 10 and the auxiliary camera module 20.

[0065] Both the main camera module 10 and the auxiliary camera module 20 are electrically connected to the control module, and the control module is used for performing fusion processing on the imaging in the main camera module 10 and the auxiliary camera module 20.

[0066] The control module is further used for electrically connecting to the active rotating member 231 and controlling the active rotating member 231 to rotate by itself through a signal; in addition, the control module can also drive the active rotating member 231 to rotate by controlling the rotation of the rotation driving member.

[0067] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the present invention in each embodiment.
